NUT-LOCK.-

SPECIFICALION forming part of Letters -Patent No. 526,896, dated October 2, 1894.

Application iiled March 7, 1894.

Colorado, have invented certain new and useful Improvements in Nut-Locks; and Ido hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the annexed drawings, makro ing a part of this specification, and to the letters of reference marked thereon, in which--` Figure 1, is a top View of the bottom orlower locking plate. Fig. 2, is a top View of the upper locking plate. Fig. 3, is a side View,

r 5 showing a portion of the bolt, and illustrating the position of the locking plates, before the nut is seated to lock the plates to the bolt. Fig. 4, is a side view, showing the plates locked tothe bolt, and the nut properly seated.

zo Fig. 5, is a top view of the nut and locking/ plates, showing the nut locking spring placed Fig. 6, shows all of the different parts placed in proper position to lock the nut and bolt. Fig. 7 is a detached z5 View of the nut locking spring.

The present invention has relation to nut locks, and it consists in the dierent parts and combination of parts hereinafter described, and particularly pointed out in the 3o claims.

Similar letters of reference indicate corresponding parts in all of the figures of the drawings. l

' In the accompanying drawings A, repre- 3 5 sents the bolt, which may be constructed of any desired length, and is provided with the ordinary screw-threads and head.

The nut B, is formed in the ordinary manner, and is attached to the bolt substantially 4o as illustrated in the drawings.

and are provided with the inclined edges b,

which inclined edges are for the purpose hereinafter described.

The top washer or plate D, is substantially of the form shown in Fig. 2, and as shown, it

5o is provided upon its opposite edges with the notches, or cut-outs c, and the shoulders d.

vided with the teeth e, which teeth are located substantially as shown in Figs. l and 2.

The washer or plate C, is provided with the curved slot, or opening f, which slot or opening is for the purpose hereinafter described. In use after the bolt A has been placed through the objects or parts designed to be clamped the washer or plates C and D, are placed on the bolt A, substantially as illustrated in Fig. 3, after which the nut B is turned onto the bolt A, in the `ordinary manner.

It will be understood that by placing the washers or plates C and D, in the position illustrated in Fig. 3, the inclined edges b, Weill come in contact with the shoulders d, and as the upper plate D is forced toward the lower plate, both plates will be forced against the screw-threaded portion of the bolt A, by means of the inclined edges b and the should ers d, which movement brings the plates C and D in to the position illustrated in Fig. 4, thereby securely seating the teeth e against the screw-threaded portion of the bolt A, thereby locking the plates C and D, to the bolt A. After the nut B, has been properly seated, and the plates C and D locked to the bolt A, the nutlocking spring is attached. The nut locking spring E, is substantially of the form shown in Fig. 7, and is preferably formed of spring steel, but other material may beA used if desired.

The spring E, is provided with the tang g, which tang is formed integral with the spring, andas shown, said tang is provided with the right angle portion g, which right angle p0rtion is for the purpose of securing the spring to the top plate D as hereinafter described.

To apply the top spring, it :is to be pressed firmly against the nut B, and the tang g, insorted in the hole of Opening h, after which the spring is pressed downward and` moved longitudinally until the tang is seated in the recess or notch h', thereby securely attaching the spring E, to the plate D, and-locking the nut B,

The curved slot or Opening f, is for the purpose of providing an opening below the openings h, for the purpose of allowing the tang g and its right angle portion g to come below the plate D. For the purpose of preventing the spring E, from tilting, after it has been properly attached the lateral arm g2, is provided, the bottom or under side of which arm cornes in contact with the top of the plate D.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the screw-threaded bolt A, the nut B, the plate or washer C, provided with the anges a having the inclined edges b, the Washer D, provided with the cutout c, and the shoulders d, the teeth e, Vformed upon the Washers or plates C and D, the openings and recesses h and h' formed upon or in the plate D, and the spring E, provided with the tang g, and the lateral arm g2, substantially as and for the purpose specified.

2. The combination of a bolt, provided with a nut, the Washer or plate C, provided with the opening f, and the flanges a, the washer or plate D, provided with the cut-outs c, and the shoulders d, the openings 71, and recesses h', and the spring E, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
